Chemical composition, larvicidal and antioxidant activities of latex from Garcinia morella (Gaertn.) Desr.

The present study revealed that the latex of Garcinia morella (Gaertn.) possessed 204.27 mg/g phenolic acid and 124.92 mg/g of flavonoid content along with other phytochemicals. Gas chromatography-mass spectrometry (GC-MS) revealed the presence of 20 compounds in the latex, with the major compounds identified as 5-Oxohexanenitrile (18.7%), phenol, 2,4-bis(1,1-dimethylethyl)- (24.64%) and Hexadecanoic acid (22.85%). The latex showed toxicity against treated third instar larvae of Culex quinquefasciatus with LC50 and LC90 values of 132.54 and 483.15 ppm. The latex also showed significant antioxidant activities with EC50 values of 205.5 µg/ml in the 1,1-diphenyl-2-picrylhydrazyl (DPPH), 95.53 µg/ml in phosphomolybdate, 308.1 µg/ml in hydrogen peroxide (H2O2) scavenging assays.
